What maintenance requirements should facility managers expect with Stick System Curtain Wall systems
Facility managers should expect a structured maintenance program for stick system curtain walls to preserve performance, appearance, and longevity. Routine inspections — typically semi-annual or annual depending on environment — should include visual checks of sealant condition, gasket integrity, weep and drainage path functionality, and anchor stability. Sealants exposed to UV and weathering generally require replacement every 7–15 years depending on product and climate; proactive replacement prevents water ingress and thermal performance degradation. Gaskets and weatherstrips can compress or harden over time; scheduled replacement of these elastomeric parts maintains air and water tightness. Glass cleaning is a regular requirement: appropriate cleaning cycles (quarterly to biannual) for urban or coastal environments prevent surface degradation, salt staining, or organic buildup; use manufacturer-recommended cleaners to protect coatings. Drainage cavities and weep holes must be cleared of debris; blocked drainage can cause pooling and infiltration. Maintenance should also include inspection of flashings and interface seals at rooflines, slab edges, and penetrations; these are common failure points. For mechanical interface elements — such as operable vents, access panels, or integrated sunshades — lubrication, hinge checks, and fastener torque verification are necessary. A maintenance log with photographs, dates, and work performed ensures traceability for warranty claims. For coastal or corrosive environments, periodic anodic or coating inspections are critical. Finally, facility managers should coordinate with façade consultants for periodic specialist assessments (every 5–10 years) to evaluate structural conditions, thermal performance, and plan major refurbishments before failures occur.
